解压文件夹中的压缩文件 Python脚本

下载了很多压缩文件，就写了一个脚本
在Python中使用winrar命令，所以一般压缩文件都支持
有些压缩文件Python中还没有相应的库
你得先把winrar添加到path环境变量中
把代码保存为rar.py
在dos下使用，如：rar.py "D:\A B\C" mkdir
#rar.py
#decompress with winrar
#arguments :filename directory opt
# opt='mkdir' to create directory with the correspond filename
# opt='direct' to decompress rar files in current directory
# opt='mk&del' to mkdir and delete rar file
import os
import sys
if len(sys.argv)!=3:
print ('wrong arguments\n')
print ('rar.py directory opt\n')
print ('opt=\'mkdir\' to create directory with the correspond filename\n')
print ('opt=\'direct\' to decompress rar files in current directory\n')
print ('opt=\'mk&del\' to mkdir and delete rar file\n')
exit(0)
#-ibck ,minimized when running
opt=sys.argv[2]
os.chdir(sys.argv[1])
for file in os.listdir('.'):
if os.path.isfile(file) and os.path.splitext(file)[1]=='.rar':
if opt=='mkdir':
cmd='winrar x -ibck "'+file+'"'+' "'+os.path.splitext(file)[0]+'"\\'
os.system(cmd)
elif opt=='direct':
cmd='winrar x -ibck "'+file+'"'
os.system(cmd)
elif opt=='mkdel':
cmd='winrar x -ibck "'+file+'"'+' "'+os.path.splitext(file)[0]+'"\\'
os.system(cmd)
os.remove(file)
else :
print('wrong option')
